Cometic 75-87 Buick V6 196/231/252 Stage I & II 4.09 inch Bore .040 inch MLS Head Gasket

If you're working on a Buick V6 engine from the mid-70s to the early 2000s, this Cometic Multi-Layer Steel (MLS) head gasket is a solid choice. It's specifically made for engines with a 4.09-inch bore and has a compressed thickness of .040 inches, fitting Stage I and Stage II performance levels. This gasket is designed to handle the demands of higher output engines, offering a reliable seal without needing any extra sealants.

Cometic builds these gaskets with multiple layers of stainless steel, which gives them increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing conditions and different surface finishes on your cylinder heads and block. This construction is great whether you're mating aluminum heads to an aluminum block or aluminum heads to a cast iron block, as it can manage the stresses that come from those combinations.

This gasket fits a wide range of Buick models like the LeSabre, Regal, and Electra, as well as some Chevrolet and Cadillac applications. It's a well-built component that aims to provide a strong seal for your engine rebuild.
